I exercise periodically but have an ok base level of fitness. I track my VO2 every couple of weeks and get variations, as I’d expect. However, the last three measurements have been exactly the same at 34.56 (55 year old female). Does this seem odd? Whilst I guess identical measurements to two decimal places are possible, I’d have thought it unlikely - but I don’t really know enough about this to know if there’s some sort of problem with my watch (series 5). Can anyone offer an explanation? Thanks.
